Just to clarify little bit. The The square Kilometre Array will have an aperture of many thousands of kilometres, but its sensitivity will only be that of 1 kmē +/- technology boosts.
The Chinese telescope will have both the aperture and sensitivity of 500 m diameter of approx 0.196 kmē.
The Chinese telescope if it is similar to the one in South America it will be able to direct its reception using a tracking device on the director mounted overhead. It will not be as good as the SKA.
